light body which moves about a horizontal axis. The motion ofthe casing about'they standandthat of the searchlightrabout its horizontal bearingshaft are carried out by means of motor-drivenv worm gears arranged in the casing or in the searchlight itself.

One embodiment of the invention is illus`y trated in the accompanying drawing, Vin y which Figures 1 and 2 are longitudinal sectionsof a searchlight according to the invention and shifted relative to one another,

Referring tothe drawing, 1 is a stationary vertical stand to thev top portion of which the cogwheel 2 of a worm' gear 2 is secured while the casing 3 is "rotatably disposed around'the stand 1.k The casing 3 carries a small reversible motor 4 the shaft of which j carries the worm 5 ofthe worm gear. Fur-v Y, AAthermore, on bothsides of the casing3 two f rotate the casing about the so that it can be turned one way or the other to Vsuit requirements and thus move they searchlight around the standl to the right or left orraise or lower itv around the pins 8. Oorrespondingly, the luminous 'cone' ofthe 55 searchlight will beL adjusted to the direction desired, which, especially in vehicles and vessels, increases considerably safety inY operation.
